Yes, assuming that pools of isopropyl alcohol exists The atmospheric temperature, in general, is too low for isopropyl to naturally exist in it's liquid form. (That is, isopropyl alcohol has a boiling point of roughly 180 Farenheit, below water.) The reason why there's water vapor in the atmosphere is a property of liquid - every liquid has a small amount ...

You cannot do this unless you allow for some finite range of EM-radiation blocking. Check out Planck's Law and Blackbody radiation formulas. In short, unless you drop an object to absolute zero temperature, it's going to radiate. You can't stop this from happening. I strongly doubt that current understanding of QED and gravity waves allow this sort of ...

A lot of questions in there, but I think overall it can work. First, gravity waves and conservation of energy. When gravity waves act on the world the do so as a transference to kinetic energy (some debate on this in physics, of course). If that is the case, then EM waves transforming into kinetic energy transforming into gravity waves should keep ...

This could work easily enough if all the EM radiation is not muffled but simply ends up somewhere else. Any light entering the area, or emitted within it, is not visible because it's not there. Electric currents would still flow, chemistry would still function and atoms and molecules would not fall apart. It might be a little chilly, but reality should not ...

Chemical Science Fire requires three things to start. The first is heat, the second is fuel, and the third is oxygen. Additionally, there's a fourth component which keeps the fire going, this is the chain reaction of the existing fire to new source materials for the first three. FMAB, also known as Full Metal Alchemist: Brotherhood, has a charcter (Lt. Col....

Nitrous oxide, as the name suggests, is already an oxide, therefore its oxygen is not that eager to bind to another atom. This is why for example carbon dioxide is used as effective fire extinguisher, because it will starve the combustion from oxidant. If you look at the Wikipedia page of this substance you will read Nitrous oxide, commonly known as ...

You should check out Ryan North's nonfiction book How to Invent Everything, it pretty much handles this exact scenario with plenty of useful details about specific technologies, including a nice tech tree. Most of what I come up with below are from his book, except for the ideas about religion. A cheat sheet version he made earlier than the book can be seen ...

Tape Measure sword A tape-measure uses a curve in the thin metal strip to impart strength. Unfortunately, the strength only runs one way. This can be countered by using two opposing spools of 'tape-measure' (or three to form a triangular blade). The tips would be joined with a hardened sharp tip. Some mechanism with interlocking teeth or magnets could help ...

Any answer to this involves a guesswork, you can really give either answer. Since there is already a good answer for "A long time," I'll give a possibility for "Not really that long." Author Liu Cixin says technology is an explosion. Humans can remain at practically the same level for tens of thousands of years, then someone formalizes the scientific ...

More than a few generations. I would assume the AI would be their (unspoken) ruler, as it knows the history and which steps to take to repeat that, which technologies to develop first for best effect, and how to keep the humans alive. But there are still a fair few things you would need to take over the world so to speak, and advance your technology. ...

Your solar system is moving through a carbon monoxide rich molecular cloud. https://en.wikipedia.org/wiki/Molecular_cloud There are regions of the cosmos occupied by immense clouds of molecules. There is a lot of hydrogen and second to hydrogen is carbon monoxide, followed by other molecules including methanol, ammonia and others. The Taurus Molecular ...

Somewhat to my surprise, there are, in fact, biological metabolic pathways that produce carbon monoxide. An enzyme that does this job is carbon monoxide dehydrogenase which pops up in various colours and flavours of bacteria and archaea. Usually it is used to oxidise CO into CO2 but it turns out you can run the process in reverse, given a suitable source of ...

Cremation does what you propose. https://slate.com/news-and-politics/2006/07/i-m-burning-up-how-much-will-my-ashes-weigh.html This estimates 3-5 pounds of ash after cremation. Volatiles leave and carbon leaves as CO2. The ash will mostly be calcium salts and oxides from the bone. Sodium and potassium salts will be present too since that is a major ...

Haloperidol Haloperidol has a dark history of being used in torture The Soviet government would administer this drug, which is normally used to treat psychiatric disorders, but when used in greater concentrations causes intense restlessness and uncontrollable shaking. Adrenaline Adrenaline has been used many times during torture to prevent people from ...

The contents of the gut just aren't under enough pressure to produce an explosion--terrorist bombs usually are in pressurized containers I believe, so that they release a large amount of energy all at once when then container breaks--otherwise, you have more of a bonfire on your hands. the max volume of gas you're looking at in the gut is about 1-1.5 liters,...

Spontaneous human combustion works on the wick effect. It's much like a candle. A small flame causes some of the fat in the person to melt and wick up into clothing or other nearby cloth. This burns just like the wick in a candle, producing additional heat. This melts additional fat. In ideal circumstances this can work its way across a large portion of a ...

Unless there's some other really bizarre things going on in this person's digestive tract, this isn't possible. As commenters have pointed out, it's not enough to have flammable materials, you need oxygen too in order for anything to burn, and there's just not enough of it in the digestive tract Under normal conditions the oxygen concentration in intestinal ...

TL;DR: yes, you can make guns just fine. What will cause you problems are lubricants and seals, and in older gunpowder firearms, things like slow match. The main issue will be that transporting gunpowder now becomes even more unsafe due to the greater chances of little sparks causing big fires. People wielding guns and operating cannon will be dangerous not ...

Burning of the gunpowder is no different in high-oxygen atmosphere - first, because it burns on itself, without contact or dependance to the atmospheric oxygen. Same for rockets: they carry their own oxydizer and propelling gases are already burnt. What will be different: Accelerated corrosion. Of everything. Most other materials will degrade faster, too. ...

The dragon may keep his breath pre-stored in glass flasks, since aqua regia does not dissolve glass. If they have access to technology, they may deliver the acid by using glass syringes (with glass needles). If not, make glass arrows or spearheads and coat them with the acid. These require a relatively low level of technology to craft. Or, you know, the ...

Sinks Like a Stone There are a lot of potential issues here, but the first one I can see is the discrepancy between a carbon-based lifeform with olivine skin and "good swimmer in the ammonia seas". Ammonia, even under low pressure (and extremely low temperatures) has a density at best three-quarters that of water. Though using ammonia in their bodies in ...

Instead of going straight to different materials, let's first look at different ways that life can manifest with the materials it already has. One way to do this is through Chirality. Chirality in chemistry is basically a description of the asymmetry of molecules, and organic molecules all seem to share a specific chirality which we call 'left handed'. We ...

Water and Sodium Bicarbonate According to the Illinois Division of Research Safety and the University of Massachusettes, the proper ways to deal with aqua regia involve water and sodium bicarbonate. Sodium bicarbonate, also known as baking soda, is a common acid neutralizer. Slow application of small amounts is best. Further, mixing water and sodium ...
